The total assignment of the 1H and 13C NMR spectra of five aromadendrane derivatives, (+)‐aromadendrene (1), (−)‐alloaromadendrene (2), (+)‐ledene (3), (−)‐dehydroaromadendrane (4), (−)‐globulol (5) and (+)‐viridiflorol (6) has been performed. The 13C spectral assignment of globulol was achieved from DEPT and double quantum coherence measurements. The concerted application of 1H1H homonuclear and 1H13C heteronuclear two‐dimensional chemical shift correlations provided other 13C and all 1H chemical shifts. Moreover, the 1H assignment for compounds 13 was reexamined from the high‐field analysis of proton‐proton coupling constants.
